Answer: 503.8
Step-by-step explanation:
since 5 - 9 goes up and 1 - 4 goes down you round the 7 to the 8 and make the 7 an 8 and make all the other numbers a 0 since you rounded up to get 503.80 or just 503.8
Answer:
18 because 6 x 3 = 18 and 9 x 2 =18
Step-by-step explanation:
D is most likely right. Basically, I would turn them into decimals and divide using a graphing calculator.
That is the formula to find the volume of a sphere. It's best to just memorize it as it is hard to come up with. The (4/3) is a constant (it is always that fraction). Pi is also a constant but it is a never ending decimal number so they use the Greek number pi to represent it. Most schools use 3.14 to equal pi but some just use 3 so be sure to check with your teacher. The r here is referring to the radius of the sphere which is the measurement from the center out to the edge. To find the volume you need to multiply (4/3) times Pi times (the radius squared)
You use Pythagorean Theorem, if u do not know what that means, the formula is this.
